Locking Devices are used for mounting, dismounting and fastening of rolling bearings and other machine parts. Rolling bearings are pressed onto the taper of a shaft or adapter sleeve by means of locknuts. The adapter sleeve can also be drawn into the tapered bearing bore. Withdrawal sleeves are pushed into the tapered bearing bore using locknuts. To remove withdrawal sleeves, a removal nut is screwed onto the sleeve thread and turned against the inner ring of the bearing until it slips out of the bearing. Nuts are used to secure the bearing on the taper (except for removal nuts). They are secured against loosening with locking devices (MB, MBL or MS).
